A system is provided for dynamically modifying media processing functions to control optimization of a media production. The system includes a media processing function library that stores media processing functions that each include a subgraph embedded therein that has pre-calculated parameters and undefined variable parameters. Media processing engines execute the plurality of media processing functions to create the media production. Moreover, the system includes a media function management controller that places the media processing functions in a job queue to be executed by one or more of the media processing engines. A resource manager receives a media production instruction from a client device to partially deploy the media processing functions in the job queue. During execution, the media processing engine can receive an input deliverable that constrains the undefined variable parameters, such that the partially deployed media processing functions is dynamically modified during runtime to create the media production.

Disclosed herein are systems and methods for generating a synopsis video. A system may receive an input video of a first duration and a request to generate a synopsis video of a second duration based on the input video. The system generates a timed text transcription of the input video and divides the timed text transcription into a plurality of sentences. The system then ranks each of the plurality of sentences based on a similarity matrix and selects a subset of the plurality of sentences that includes highest ranked sentences of the plurality of sentences, with the subset having a summed time duration that is less than or equal to the second duration. The system extracts and combines respective clips from the input video that correspond to the selected subset of sentences to generate the synopsis video.

Moreover, storing the new materials data file in the media file system, and updating the file relationship graph using the new materials data file.

Media file systems and methods of storing media files in a media file system

A system that dynamically provides media essence to a client device. An I/O interface receives a media access request that defines a range of media content at a defined format, and a VFS generates an essence containing file that includes a file name and extension that identifies byte ranges for the content range and the defined format; dynamically builds the essence containing file to comprise APIs that can access at the identified byte ranges for the defined range of media content; imposes a structure on a portion of bytes contained in the essence containing file to define a processing function to be executed before delivering the essence to the client device; and opens the essence containing file to access the identified byte ranges using the APIs and causing the processing function to be executed on the accessed and identified byte ranges before delivering the essence to the client device.

Virtual file system for dynamically providing media content

A system is provided for optimizing the distribution of media production resources. The system includes a grain store having a persistent file system that stores essence grains upon receipt into individual files according to a folder layout. The system also includes a grain store manager that dynamically names the individual files upon receipt of the essence grains to configure the folder layout to form a natural index that maps bytes of the essence grains to a numerical index of the essence grains, respectively, generates a descriptor for flows of files in the folder layout, generates a unique identity for a plurality of sources in the grain store, and receives a media access request from a client device application based on a media production workflow. The grain store then dynamically accesses the essence grains by identifying the unique identity of the respective group of flows and the descriptor for the format.

A media file system, apparatus, computer program product and method are provided for of streaming media file data. An exemplary method includes receiving a request for media file data for a desired time, and determining from the desired time an available segment of media file data, wherein the segment includes media file data from a start time to an end time. The method further including returning the available segment of media file, wherein the step of returning the available segment of media file data includes returning information indicative of the start time to end time covered by the media file data of the available segment.

Methods of streaming media file data and media file servers

A method of providing file data for a media file of a pre-determined format from a file system comprising a file record database and a data store, wherein the media file corresponds to a programme consisting of a plurality of segments, and wherein the segments included in the programme are dynamically determined. The method comprising the steps of receiving details of the programme including the duration of the programme, and determining the layout of the media file in the pre-determined format from the received details of the programme, the layout including locations for essence data within the file. A file record for the media file in the file record database is then created. In response to a request for the location of essence data within the file, a location given by determined layout of the media file is returned. Further, in response to an instruction that a segment is to be included in the programme, essence data corresponding to the contents of the segment is obtained. Then, in response to a request for a portion of essence data from the media file corresponding to a time period of the programme, essence data derived from the received essence data according to the determined layout of the media file is returned.

Methods and systems for providing file data for a media file

A system is provided for configuring legacy file-based workflows to remotely and dynamically access media essence. An example system includes a filename generator that dynamically generates a filename for corresponding media content in an essence store in response to a selection by a file-based workflow application running on a media production computing device. The system includes an identity file generator that generates a respective identity file for the selected content and that includes the generated filename. Furthermore, the system includes a content API that queries an essence access database using the generated identity file to obtain metadata that indicates access information for the media content. The content API then configures the file-based workflow application to access the media content from the essence store based on an accessed track number and byte length of the respective media content accessed in response to the query of the media essence access database.
